Stanadyne Performance Formula Diesel Fuel Additive 16 oz — Cleans Injectors & Boosts Cetane (Case of 12)

Formulated for modern diesel systems, this Performance Formula pint treats up to 60 gallons of diesel per bottle and is widely recommended by vehicle and engine OEMs where Stanadyne approvals apply. It combines detergents, cetane-boosting agents, and lubricity improvers into a single year-round treatment intended to address common fuel-related issues in ultra-low-sulfur diesel (ULSD).

How does this additive improve engine performance?

Performance Formula works by cleaning deposits in the injection system and by improving combustion quality through a cetane increase. Cleaner injectors atomize fuel better, which supports smoother running and can lead to modest horsepower recovery.

• Detergent package removes injector and intake deposits.
• Cetane improver promotes more complete combustion.
• Improved spray pattern helps throttle response and idle quality.

Will it reduce fuel consumption and emissions?

Independent tests have shown average fuel economy gains and reductions in smoke and particulate emissions when fuel systems run cleaner and combustion is optimized. Benefits vary with engine type, driving conditions, and baseline fuel quality.

• Average observed MPG improvement around 4%, with higher gains possible.
• Reduces visible smoke and particulate output by improving combustion.
• Helps restore efficiency lost to injector deposits and poor atomization.

Does it protect fuel system components and cold-starting?

The formula includes lubricity enhancers to protect pumps and injectors that are challenged by ULSD’s reduced natural lubricants. Enhanced lubricity and cetane improvements can also help cold-start performance and reduce injector wear over time.

• Lubricity additives restore protection to pumps and injectors.
• Less wear and scuffing in high-pressure components.
• Cetane boost supports easier starting and steadier idling in cool conditions.

How should I use Stanadyne Performance Formula and can it be mixed with other products?

Use the product as directed on the bottle: one 16 oz bottle treats approximately 60 gallons of diesel. Stanadyne additives are compatible with one another and may be blended; double-dosing is not harmful but does not necessarily double results.

• Dosage: 16 oz treats ~60 gallons of diesel (follow label guidance).
• Compatible with other Stanadyne additives; safe to blend per directions.
• Intended for year-round use to maintain fuel system cleanliness and protection.

Who is this for: Stanadyne Performance Formula is suited for commercial fleets, owner-operators, boaters, agricultural and construction equipment owners, and passenger diesel vehicle drivers who want a single additive to address injector deposits, lubricity loss from ULSD, and modest cetane shortfalls. It’s particularly useful where OEMs specify or recommend Stanadyne products and for anyone looking to maintain reliable injection performance and reduce fuel-related issues across a range of diesel engines.
